UP Opens New Kate Shelley Bridge
Representing an investment of more than $50 million by Union Pacific, the bridge improved operating efficiency and increased freight capacity on the railroad's busy corridor linking Chicago to the West Coast. The new Kate Shelley Bridge, located west of Boone, Iowa, is more than 2,800 feet long and 190 feet high, making it one of the tallest double-track railroad bridges on the continent. It was designed to handle today’s heavy trains traveling at speeds up to 70 mph. The new bridge replaced a steel structure built in 1901 by the Chicago & North Western.
